在我的项目中，我一直在XYZ war中使用ABC jar，两者都使用 Spring 3.1 实现ehCache，xml 驱动的配置（我们有 ehCache.xml 和 spring-context.xml，我们在两个项目中都通过 Spring AOP 拦截缓存） . 我们收到以下错误：

java.lang.IllegalArgumentException: Cannot find cache named [xxxxxx] for CacheableOperation[] caches=[Cxxxxxxxx] | condition='' | key='#xxxxxxxxxxxxx'

解决方案：

这就是我们解决这个问题的方法：

  1. 我们将所有缓存配置从ABCehCache.xml（来自 ABC jar）复制到XYZehCache.xml（来自 XYZ war）。
  2. 我们删除了ABCehCache.xml（从 ABC jar 中），但里面的所有配置（如 bean 实例化ehCache.xml和 Spring AOP）ABC-spring.xml都将保持不变。
  3. 在XYZ-spring.xml中，我们导入ABC-spring.xml并定义了复合缓存管理器。

支持的配置文件：

ABC-spring.xml：

    <aop:aspectj-autoproxy proxy-target-class="true" />

    <bean id="CacheManager1" class="org.springframework.cache.ehcache.EhCacheCacheManager">
        <property name="cacheManager" ref="ehcache"></property>
    </bean>

    <bean id="ehcache"
        class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"
        p:config-location="classpath:ABCEhcache.xml" />

XYZ-spring.xml：

<import resource="classpath*:ABC-spring.xml" />
<aop:aspectj-autoproxy proxy-target-class="true" />

    <bean id="cacheManager" class="org.springframework.cache.support.CompositeCacheManager">
    <property name="cacheManagers">
        <array>
            <ref bean="CacheManager1" />
            <ref bean="CacheManager2" />
        </array>
    </property>
    <property name="fallbackToNoOpCache" value="true" />
</bean>

    <bean id="CacheManager2" class="org.springframework.cache.ehcache.EhCacheCacheManager"
        p:cache-manager-ref="ehcache" />
    <bean id="ehcache"
        class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"
        p:config-location="classpath:XYZEhcache.xml" />

希望这会有所帮助！
